new to the drawing, which i'ornis a part of this invention, I have shown a particular type of fastener element secured to acarrying .medium in such a mannerr as to illustrate one particular application' of my invention. It is to be underetoodhowever, that my invention is applicable to many types of sockets, studs, buttons and theflike and, therefore,` the embodiment of the invention shown is for illustrative purposes only.

In -Fig. l of the Vdrawing I have illustrated a well-known type of socketr l having a fabric engaging surface '2 `engaged with one face of a flexible carrying ymedium 3 and secured thereto by a rivet portion 4 pressed irom the socket side view/of thecap shown in casing and extending through the carrying medioutwardly adjacent tothe outer periphery of the turning means. Thus, the metal isr pressed downwardly to form a double'wallrwhich is bent Ainwardly to provide clenching means "I to prevent separation of lthe parts after they have been secured together, as clearlyjillustrated in Fig. 1. The metalof the attachingA plate or cap 5 beyond the double wall portion is of substantial "area and may be of any desired shape. This metal provides a fabric-engaging surface 3 which cooperates with the fabric-engaging surface Zof the socket or .other element 1, thereby to grip the exible carrying medium 3 between the attaching'cap 5 and the socket 1. .f y, f

One ofthe important features of rnyinven` tion is in thelocation ofthe attaching means cen-` trally of the two parts which are to be .secured together.- ,Heretofora it has been the usual practice to'provide the turning and clenching means e on either the cap or vthe fastener element adja-Kk cent to the peripheral edge and provide attaching prongs or a tubular rivet for engagement therewith. With that type of attachment the carrying medium had to be penetrated relatively close to the edges of the parts and in many instances when the carrying medium was placed means is on the attaching cap or the fastener part, there is a decided advantage because the carrying medium is penetratedat a point rela'- tively remote from the edges of the cap and fastener element. Furthermore, a substantial area of the carrying medium is gripped tightly between the two parts between the edges thereof and the' penetratingY element of the attaching means to provide a strong, durable attachment. The fastening means which I have illustrated and described is relatively simplev to manufacture and is so arranged that the parts of a givenV installation may be easily and quickly assembled.`

While I have illustrated and described a preferred embodiment of my invention, it` should beV understood thatY I do not wish to be limited thereby, because the scope of 'my invention is best set forth in the following claims.

What is claimed, f i LA fastener niember'installation comprising,

in combination, a carrying medium, a snap fasl tener member for cooperativeengageinent with anotherrsnap fastener member and a one-piece attaching plate having an outer surface which extends' from the'periphery `of .the attaching plate in an upwardly curved direction for a substantial distance towardthe center, annular anvil and clenching means located in the central portion of said attaching plate remote from thek periphery thereofand a shank ,extendingfrom said snap fastener member through the carrying medium and having its free end upset by and engaged with the anvil and clenching means of the attaching plate tosecure the parts of the installation together.

2. A fastener member installation comprising, in combination, a carrying medium, a snap fastener member for cooperative engagement with another snap fastener member and a onepiece sheet metal attaching plate, said attaching plate having integral annular anvil and clenching means located adjacent to the center thereof and remote from the periphery thereof and having its outer edge turned under to provide a smooth portion of substantial width in engagement with the carrying medium, and a tubular rivet extending from said snap fastener member through the carrying medium and upset by and engaged with the anvil and clenching means of the attaching plate to secure the parts of the installation together.

3. An attaching plate for snap fastener and like installations comprising a central depressedv portion surrounded by an outwardly flaring wall from the bottom of the depressed portion to provide turning means, an inwardly turned double wall portion, each portion contacting with the other and'surrounding the wall of the central depressed portionto provide elenching means and to provide the attaching plate with a substantially continuous outer surface extending from the periphery of the attaching plate in an upwardly and inwardly extending direction toward the center and a support-engaging surface of substantial width located between the inwardly turned walls and the periphery of the said plate.

l4. An-attaching plate for snap fastener and like installations comprising a central depressed portion having an outwardly aring wall from the bottom of the depressed portion to provide turningrmeans for upsetting attaching means provided by the snap fastener, an integral wall extending downwardly and inwardly from the pe riphery of said depressed portion, a second wall integral with said first wall and extending outwardlyand upwardly in close proximity to said first wall to a point adjacent to the periphery of said depressed portion and said attaching plate having a portion of substantial area extending outwardly in all directions from said second wall' adjacent to the periphery of said depressed portion thereby providing a relatively continuous smooth outer surface from the periphery of the depressed portion to the periphery of the attaching plate.
